Importing a Yacht Into the US: Duties, Steps & Costs

A 50-foot motor yacht you found in the Mediterranean might cost a third less than its near-twin sitting in a Florida marina. That gap is real, and it's why thousands of American buyers shop abroad every year. But the sticker price is only the start of the math. Once a foreign-built or foreign-located boat crosses into US waters, it runs into customs duty, federal fees, Coast Guard requirements, state taxes, and a paperwork chain that can stall a deal for weeks if you handle it badly.

The good news: importing a yacht into the US is a well-worn path. The rules are public, the duty rate is modest by global standards, and most of the work can be handled by a customs broker for a few hundred dollars. The trick is knowing what you owe, when you owe it, and which steps you cannot skip. This guide walks through the whole process — the 1.5% duty, the HMF and processing fees, EPA and Coast Guard rules, the customs entry itself, and the state sales or use tax that often dwarfs the federal bill.

The 1.5% duty: what you actually pay to US Customs

For most recreational yachts, the headline number is small. Under the Harmonized Tariff Schedule of the United States (HTSUS), sailboats and motor yachts for pleasure generally fall under heading 8903, which carries a general duty rate of 1.5% of the customs value.

That value is the price you paid for the boat (the transaction value), converted to US dollars. On a $400,000 yacht, the federal import duty is roughly $6,000. Compared to the 20%+ VAT a European buyer pays, that's modest — which is part of why US-flagged ownership of foreign-built boats is common.

A few important wrinkles:

• Country of origin matters less than you'd think. The 1.5% general rate applies to most trading partners. Boats built in countries without normal trade relations face the much higher "Column 2" rates, but that rarely affects mainstream European, UK, or Asian builders.
• Trade agreements can zero it out. Boats that qualify under certain free trade agreements may enter duty-free, but qualification depends on where the boat was actually manufactured and documented — not just where you bought it. Don't assume; verify with a broker.
• Tariff actions change. Additional or punitive tariffs have been layered onto goods from specific countries in recent years. The base rate is stable, but always confirm current rates before you commit, because a surprise surcharge can blow up your budget.

How customs value is calculated

Customs assesses duty on the value of the boat at the time of import, plus certain costs. Generally that's the purchase price. If you bought the boat cheap and then poured money into a refit abroad before importing, those improvements can be added to the dutiable value. Freight and insurance to bring the boat to the US are typically not part of the customs value for duty purposes (the US uses FOB-style valuation), but they absolutely affect your total landed cost.

Keep clean documentation: the bill of sale, wire transfer records, and the builder's information. Customs can and does question values that look artificially low.

The fees beyond duty: HMF, MPF, and user fees

Duty is rarely the only line item. Depending on how the boat arrives, you may also owe:

• Harbor Maintenance Fee (HMF): 0.125% of the cargo value, charged on goods arriving by vessel through certain ports. On a boat shipped on a cargo ship, this applies to the boat's value. On a $400,000 yacht that's $500.
• Merchandise Processing Fee (MPF): A processing charge on formal entries, calculated as a percentage of value within a set minimum and maximum (the cap is a few hundred dollars). For most yacht imports it lands at the maximum.
• Customs broker fee: $200–$600 for a straightforward yacht entry, more if the deal is complex or involves multiple agencies.

These are small relative to duty on a large boat, but on a modest used boat they're proportionally bigger. Budget for them rather than being surprised at clearance.

How the boat physically arrives — and why it changes the paperwork

There are two common ways a foreign-located yacht reaches the US, and the method affects your customs entry.

Shipped on a cargo ship (transport vessel)

Smaller boats and many sailboats travel as cargo on a freighter or a dedicated yacht transport ship. The boat is loaded in the origin country and unloaded at a US port. In this case it's treated like any imported merchandise: it arrives, you (or your broker) file a formal entry, pay duty and fees, and Customs releases it.

This is the cleanest path for boats under roughly 45–50 feet, and transport costs typically run anywhere from $15,000 to $50,000+ depending on size, route, and whether the boat ships on its own keel in a cradle or inside a float-on/float-off carrier.

Delivered on its own bottom

Larger yachts often cross under their own power or under sail — a transatlantic delivery, or a run up from the Caribbean. The boat arrives as a "vessel" rather than cargo, which changes the entry mechanics. The captain must report arrival to Customs and Border Protection (CBP) immediately on reaching the first US port, and the formal import entry is then filed.

Delivery on its own bottom saves shipping money on big boats but adds delivery crew costs, fuel, insurance for the passage, and wear on the boat. It also means the import formalities happen at whatever port you make landfall, so plan the entry paperwork before you arrive.

Step-by-step: the import process from offer to clearance

Here's the realistic sequence for importing a yacht you're buying abroad.

1. Confirm the boat's tariff treatment and value

Before you sign anything, establish the duty rate that applies and roughly what your landed cost will be. A customs broker or marine import specialist can give you this in a day. Get it in writing so your budget is real.

2. Structure the purchase and survey

Buy the boat the same careful way you'd buy domestically — survey, sea trial, clear title. The fact that it's abroad doesn't change the fundamentals. If anything, do more diligence, because chasing warranty or fraud claims across borders is painful. Our guides on how to buy a used yacht without getting burned and the sea trial checklist apply directly here. Use a surveyor with the right credentials — see SAMS vs NAMS vs IIMS.

3. Arrange transport or delivery

Book a yacht transport company or a delivery captain. Get the boat insured for the passage or the shipping leg specifically — your normal policy may not cover an ocean transport.

4. Hire a licensed customs broker

You can self-file, but for a one-time import it rarely pays to learn the system. A broker prepares CBP Form 7501 (the entry summary), handles the bond, calculates duty and fees, and clears the boat. Provide them the bill of sale, build details, and arrival information.

5. File the entry and pay duty and fees

When the boat arrives at the US port of entry, the broker files the formal entry. You pay the 1.5% duty plus HMF, MPF, and any surcharges. A single-entry customs bond is usually required (the broker arranges it); it's a small percentage of the value.

6. Clear EPA and Coast Guard requirements

This is where importers get tripped up. More below — but in short, the boat's engines must meet US emissions standards and you'll file EPA Form 3520-21, and the boat itself should meet US Coast Guard safety and construction standards.

7. Document or title and register the boat

After clearance, you either federally document the yacht with the US Coast Guard (common for boats 5 net tons and up) or title and register it in your state. Then you deal with state sales or use tax.

EPA emissions and the engine question

US emissions rules for marine engines are a genuine hurdle for some imports. The EPA requires that imported boat engines either be certified to US emissions standards or qualify for an exemption. You'll file EPA Form 3520-21 at the time of import declaring the engines' status.

What this means in practice:

• Engines built for the US market or to EPA-compliant standards clear without drama. Many major engine makers build to global standards that satisfy the EPA.
• Engines built only to other standards can be a problem. In some cases an independent commercial importer (ICI) must modify and certify the engine — expensive and slow — or the engine may not be importable at all.
• Older boats may predate certain rules and qualify under different provisions, but don't assume; check the model year and engine certification.

Confirm engine compliance before you buy. A non-compliant pair of engines can turn a bargain into a project, or kill the import entirely.

US Coast Guard standards and documentation

A boat built for another market won't automatically carry US Coast Guard (USCG) compliance markings. For recreational boats, USCG standards cover things like flotation, fuel systems, electrical, and capacity labeling. Many quality foreign builders meet or exceed these, but the boat may lack the specific US labels and the manufacturer's certification.

In practice, recreational yachts are usually imported without re-certification — the standards apply primarily to manufacturers and first sale — but you should make sure the safety equipment aboard meets US carriage requirements before you operate domestically.

Documenting vs state registration

Once imported, you choose how to register:

• USCG documentation: Available for boats of at least 5 net tons (most yachts over ~26–30 feet qualify). Documentation is federal, useful for financing, and required for some offshore and charter uses. It does not replace state tax obligations.
• State titling and registration: Required in most states regardless, and the only option for smaller boats.

Many owners document federally and still register (or pay use tax) in their home state.

State sales and use tax: often the bigger bill

Here's the number that surprises buyers: the federal duty is 1.5%, but state sales or use tax can be 6% or more, applied to the same boat. That can easily exceed the duty several times over.

How it works:

• You generally owe sales or use tax in the state where you'll keep and use the boat, based on the purchase price.
• Rates vary widely. Some states have tax caps on boats — Florida caps sales tax at $18,000, for example — which is a major reason boats cluster in those states.
• A handful of states have no sales tax or favorable treatment for boats kept out of state for a period.
• Use tax applies even if you bought the boat elsewhere; it's the counterpart to sales tax for things you bring in.

The interaction between import duty, federal documentation, and state tax is where smart structuring saves real money — legally. Some buyers keep the boat in a cap state, or use offshore closing and delivery arrangements. This is worth a conversation with a marine tax advisor, not guesswork.

A worked example: total landed cost

Say you buy a 48-foot motor yacht in Italy for $450,000 and ship it to Florida.

• Purchase price: $450,000
• Import duty (1.5%): ~$6,750
• HMF (0.125%): ~$563
• MPF: capped at a few hundred dollars
• Customs broker + bond: ~$600–$1,200
• Yacht transport (Med to US East Coast): ~$30,000–$45,000
• Marine insurance for transport: varies, often 1–2% of value for the voyage
• Florida use tax (6%, capped at $18,000): $18,000
• Survey, sea trial, travel, miscellaneous: $5,000–$10,000

Your federal import duty is under $7,000 — but your all-in cost to land the boat is closer to $510,000–$525,000. The duty is the small part. Transport and state tax dominate. Run this math for your boat and your state before you decide whether the overseas bargain is actually a bargain.

Common mistakes that cost importers money

• Assuming duty-free. People hear "1.5%" or "free trade" and assume nothing is owed. Confirm the actual rate and watch for added tariffs.
• Ignoring EPA engine compliance. The single most expensive surprise. Check it before the survey.
• Forgetting state use tax. The federal side is cheap; the state side isn't. Budget for it from day one.
• Underdeclaring value. Tempting, illegal, and risky. Customs penalties and seizure are real, and lenders and insurers want a true value anyway.
• No transport insurance. Ocean shipping and deliveries go wrong. A dropped boat without coverage is catastrophic.
• Skipping the survey because it's far away. Distance is not a reason to fly blind. Hire local, qualified, independent surveyors.
• DIY customs filing on a deadline. A botched entry holds the boat at port, accruing storage. A broker is cheap insurance.

FAQ

How much is the import duty on a yacht into the US?

Most recreational yachts carry a general duty rate of 1.5% of the customs (purchase) value under HTSUS heading 8903. On a $300,000 boat that's about $4,500. Additional fees (HMF at 0.125%, MPF, broker, and bond) apply, and certain countries may face extra tariffs, so confirm current rates before buying.

Do I have to pay sales tax on top of import duty?

Usually yes. Federal import duty and state sales or use tax are separate. Most states charge sales or use tax (often around 6%, sometimes capped) on a boat you keep and use there — and that bill frequently exceeds the federal duty by several times. Talk to a marine tax advisor about where the boat will be based.

Can I import a boat with non-US engines?

Sometimes. The EPA requires imported marine engines to meet US emissions standards, declared on Form 3520-21. Engines built to compliant global standards clear easily; engines built only to other standards may need costly certification by an independent commercial importer, or may not be importable. Verify engine compliance before you buy.

Do I need a customs broker to import a yacht?

It's not legally required, but for a one-time import it's almost always worth it. A broker handles the entry summary, the customs bond, duty and fee calculation, and clearance — for a few hundred dollars. Mistakes on a self-filed entry can leave the boat stuck at port racking up storage charges.

Should I ship the boat or deliver it on its own bottom?

Smaller boats (under ~45–50 feet) usually ship on a transport vessel — cleaner paperwork and less wear. Larger yachts often come under their own power, which saves shipping cost but adds delivery crew, fuel, and passage insurance. Either way, insure the leg specifically and plan the customs entry before arrival.

Can I avoid US import duty legally?

There are legitimate structures — qualifying free-trade-agreement origin, keeping the boat foreign-flagged and cruising under a cruising permit without formally importing, or basing in a low-tax state. Each has strict rules and trade-offs. "Avoiding" duty by underdeclaring value is fraud. Get professional advice rather than improvising.
